inline

Returns whether skybox is enabled.

Definition at line 288 of file qgs3dmapsettings.h.

◆ isTerrainShadingEnabled()

bool Qgs3DMapSettings::isTerrainShadingEnabled ( ) const

inline

Returns whether terrain shading is enabled.

When enabled, in addition to the terrain texture generated from the map, the terrain rendering will take into account position of the lights, terrain normals and terrain shading material (ambient and specular colors, shininess).

Since: QGIS 3.6

Definition at line 240 of file qgs3dmapsettings.h.

◆ layers()

QList< QgsMapLayer * > Qgs3DMapSettings::layers ( ) const

Returns the list of map layers to be rendered as a texture of the terrain.

Note: If terrain map theme is set, it has a priority over the list of layers specified here.

Definition at line 378 of file qgs3dmapsettings.cpp.

◆ layersChanged

void Qgs3DMapSettings::layersChanged ( )

signal

Emitted when the list of map layers for terrain texture has changed.

◆ mapThemeCollection()

QgsMapThemeCollection* Qgs3DMapSettings::mapThemeCollection ( ) const

inline

Returns pointer to the collection of map themes.

Normally this would be QgsProject::mapThemeCollection() of the currently used project. Without a valid map theme collection object it is not possible to resolve map themes from their names.

Since: QGIS 3.6

Definition at line 135 of file qgs3dmapsettings.h.

◆ mapTileResolution()

int Qgs3DMapSettings::mapTileResolution ( ) const

Returns resolution (in pixels) of the texture of a terrain tile.

This parameter influences how many zoom levels for terrain tiles there will be (together with maxTerrainGroundError())

Definition at line 427 of file qgs3dmapsettings.cpp.

This parameter decides how aggressively less detailed terrain tiles are swapped to more detailed ones as camera gets closer. Each tile has its error defined in world units - this error gets projected to screen pixels according to camera view and if the tile's error is greater than the allowed error, it will be swapped by more detailed tiles with lower error.

Definition at line 413 of file qgs3dmapsettings.cpp.

◆ setOrigin()

void Qgs3DMapSettings::setOrigin ( const QgsVector3D & origin )

inline

Sets coordinates in map CRS at which our 3D world has origin (0,0,0)

We move the 3D world origin to the center of the extent of our terrain: this is done to minimize the impact of numerical errors when operating with 32-bit floats. Unfortunately this is not enough when working with a large area (still results in jitter with scenes spanning hundreds of kilometers and zooming in a lot).

Need to look into more advanced techniques like "relative to center" or "relative to eye" to improve the precision.
